Kellogg-Briand Pact

8/27/1928

Coolidge's best-known initiative was the Kellogg–Briand Pact of 1928, named for Coolidge's Secretary of State, Frank B. Kellogg, and French foreign minister Aristide Briand. The treaty, ratified in 1929, committed signatories including the United States, the United Kingdom, France, Germany, Italy, and Japan to "renounce war, as an instrument of national policy in their relations with one another." The treaty did not achieve its intended result – the outlawry of war – but it did provide the founding principle for international law after World War II
